Earl Rudolph "Bud" Powell (September 27, 1924 – July 31, 1966) was an American jazz pianist and composer. Along with Charlie Parker, Thelonious Monk, Kenny Clarke and Dizzy Gillespie, Powell was a leading figure in the development of modern jazz. His virtuosity led many to call him the Charlie Parker of the piano. Powell was also a composer, and many jazz critics credit his works and his playing as having "greatly extended the range of jazz harmony".
One of the giants of the jazz piano, Bud Powell changed the way that virtually all post-swing pianists play their instruments. He did away with the left-hand striding that had been considered essential earlier and used his left hand to state chords on an irregular basis. His right often played speedy single-note lines, essentially transforming Charlie Parker's vocabulary to the piano (although he developed parallel to "Bird").
He was born in Harlem, New York, United States. Powell's father was a stride pianist. Powell started classical piano lessons at the age of five. His teacher, hired by his father, was a West Indian man named Rawlins. At 10 years of age, Powell showed interest in the swing music that could be heard all over the neighbourhood. He first appeared in public at a rent party, where he mimicked Fats Waller's playing style. The first jazz composition that he mastered was James P. Johnson's "Carolina Shout". Powell's older brother, William, played trumpet and violin, and by the age of 15 Powell was playing in William's band. Powell heard Art Tatum on the radio and tried to match his technique. Powell's younger brother, Richie Powell, was also a noted bebop pianist.
In his youth Powell listened to the adventurous performances at Uptown House, a venue near his home. This was where Charlie Parker first appeared as a solo act when he briefly lived in New York. Thelonious Monk played at Uptown House. When Monk met Powell he introduced Powell to musicians who were starting to play bebop at Minton's Playhouse. Monk was a resident pianist, and he presented Powell as his protégé. Their mutual affection grew, and Monk became Powell's greatest mentor. Powell eagerly experimented with Monk's idea. Monk's composition "In Walked Bud" is a tribute to their time together in Harlem.
Powell was engaged in a series of dance bands, his incubation culminating in becoming the pianist for the swing orchestra of Cootie Williams. In late 1943 he was offered the chance to appear at a nightclub with the quintet of Oscar Pettiford and Dizzy Gillespie, but Powell's mother decided he would continue with the more secure job with the popular Williams from 1943.
Powell was the pianist on a handful of Williams's recording dates in 1944. The last included the first recording of Monk's "'Round Midnight". His job with Williams was terminated in Philadelphia in January 1945. After the band finished for the night, Powell wandered near Broad Street Station and was apprehended, drunk, by the private railroad police. He was beaten by them and incarcerated briefly by the city police. Ten days after his release, his headaches persisted and he was hospitalized at Bellevue, an observation ward, and then in a state psychiatric hospital sixty miles away. He remained there for two and a half months.
Powell never fully recovered and would suffer from bad headaches and mental breakdowns throughout the remainder of his life. Powell resumed playing in Manhattan after his release. In 1945–46 he recorded with Frank Socolow, Sarah Vaughan, Dexter Gordon, J. J. Johnson, Sonny Stitt, Fats Navarro, and Kenny Clarke. Powell became known for his sight-reading and his skill at fast tempos and recorded some true gems during 1947-1951 for Roost, Blue Note, and Verve, composing such major works as "Dance of the Infidels,""Hallucinations" (also known as "Budo"), "Un Poco Loco,""Bouncing with Bud," and "Tempus Fugit." Even early on, his erratic behaviour resulted in lost opportunities (Charlie Parker supposedly told Miles Davis that he would not hire Powell because "he's even crazier than me!"), but Powell's playing during this period was often miraculous.
A breakdown in 1951 and hospitalization that resulted in electroshock treatments weakened him, but Powell was still capable of playing at his best now and then, most notably at the 1953 Massey Hall Concert. Generally in the 1950s his Blue Notes find him in excellent form, while he is much more erratic on his Verve recordings. After several more periods in the hospital, Powell moved to Paris. His warm welcome and lengthy stay (1959-1964) extended his life a bit, but even here Powell spent part of 1962-1963 in the hospital.
In 1963, Powell contracted tuberculosis. During the next year, he returned to New York to perform at Birdland with drummer Horace Arnold and bassist John Ore. His performances during these years were adversely affected by his alcoholism. His emotions became unbalanced, and he was hospitalized in New York after months of erratic behaviour and self-neglect. On July 31, 1966, he died of tuberculosis, malnutrition, and alcoholism. He was given the last rites of the Catholic Church
